It's a Photoshop doodle inspired by the incredible pictures of Saturn and its moons sent back by the Cassini space probe. Since there are exoplanets, there are probably ones that look just like Saturn but have twisted aurora bands instead of rings. And they would have exomoons made from rock and ice and liquid which look like the crunchy moons of Saturn that the space probe revealed. I call that "exo-lent." In the endless variety of our universe, anything planetary can happen.
